Why is meiosis important for sexual reproduction?

• It allows the zygote formed from fertilization to have triple the chromosome number of the organism. 
• It allows gametes to have twice the original number of chromosomes of the organism.
• It allows gametes to have half the original number of chromosomes of the organism. 
• It allows the zygote formed from fertilization to have half the original number of chromosomes of the organism.
